An adaptive tracking method for ground target in FLIR image including centric and eccentric tracking is presented in this
paper. The eccentric tracking is adopted to assist ATR or manual target acquisition by stabilizing the light axis of the
seeker. The tracking adaptability detection at the start of centric tracking avoids tracking bad locked point and decreases
the shift, slide and jump in the subsequent tracking. Combination of periodic template-updating based on scale variance
rate and interruptive template-updating based on supervision of tracking point enhances the adaptability of tracking
template. Supervision, modification of current tracking point and the combination of direct and indirect tracking increase
the stability of tracking system. The multi-scale and size-variable template is adopted to fit the variable target scale. The
detection and adoption of occlusion mask increase the accuracy of the tracking system. The hardware system based on
multi-DSP takes a real-time parallel processing. The trial results show that this method is efficient to reduce the
possibility of shift, slide, and jump in ground target tracking comparing with the traditional correlation tracking method.
